I thought Miuccia didn't like the whole celeb obsession (particularly the extra trashy kind). I though that's why she doesn't have celebs lining her front rows at shows, etc. Not that Prada is neccesarily a super bastion of singular good taste, but I really don't see her choosing Simpson for anything.
Texas Pageat Hair. That is the most perfect discription. In this monthes Bazaar, I believe, there is an article about Ken, and Jessica, and the wig/extension company they have. In it they say that Jessica only wears wigs because a few years ago, some other stylist cut off her hair or something, I guess her hair grows really slowly

I think most celebs hair usually looks really awful, and fake. They mention Britney in the article also, saying that you don't want your hair to look like that, but I don't see to much deference between Simpson and Spears, maye just that Simpson has more people styling her.
Of course Lohan isn't any better. Lets just hope the whole story is fictitious I guess.
